Functional surgery for treatment of 149 cases of cancer of vestibule of larynx admitted to the Institut Gustave-Roussy, Paris, included 92 supraglottic horizontal laryngectomies and 57 reconstructive subtotal laryngectomies with crico-hyoidopexy. General selection criteria for performing subtotal laryngectomy were very strict: local criteria included tumor of vestibule with possible extension to ventricle, to an arytenoid cartilage or to the HTE space, and regional criteria, more particularly, required absence of any palpable gland or mobile gland of less than 2.5 cm. This rigorous selection explains excellent carcinologic results: 90.8% survival after 5 years following subtotal laryngectomy as against 37.9% after supraglottic horizontal laryngectomy, equivalent to a survival rate for all cases of cancer of vestibule of larynx treated by functional surgery of 65% at 3 years and 58% at 5 years.
